LAND-ROLLER.

Application filed September 1., 1914.

T all whom it mail concern:

Be it known that I, HOMER H. ARNn'rT, a citizen of the United States, residing at Osgood, in the county of Darke and State of Ohio, have invented certain new and useful Improvements in Land-Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to rollers, of both land rolling and clod crushing types.

An object of the invention is the provision of a roller of hollow formation and having means whereby a suitable filling may be placed therein to increase its weight.

Another object is to provide a roller composed of inner and outer spaced drums, and a reinforced cement filling between the drums for adding weight and giving rigidity t9 the device.

Another object is to provide a land roller or clod crusher of simple and durable construction, and one which may be manufactured at a comparatively low price.

A further object is to reinforce either the outer or the inner surface of the cement body or drum and also the ends thereof with a covering of sheet metal if deemed necessary, or said covering may be wholly or partly omitted if desired.

In the accompanying drawing, Figure 1 represents a perspective view of the land roller. Fig. 2 represents a longitudinal sectional view through one of the roller members. Fig. 3 represents a vertical sectional view therethrough, and Fig. 4 represents a frag mentary sectional view through a modified form of outer drum.

Referring to the drawing, the numeral 5 indicates the frame of the roller having de pending brackets 6, carrying bearing blocks 7 within which is journaled a shaft 8. A draft pole 9 is attached. to the frame 5 and carries a suitable seat 10.

A pair of rollers 11 is rotatably mounted over the shaft 8 and upon opposite sides of the intermediate brackets 6. Each roller is composed of an outer cylindrical drum 12 and an inner cylindrical drum 13 of con siderably less size than the first drum, thereby leaving a space between these parts. Each of the drums 12 and 13 is provided at opposite ends with a concentric opening through which is positioned a sleeve or hub Specification of Letters Patent.

Serial No. 859,644:.

1 1. Portions of the ends of the outer drums 12 are bulged inwardly at 15 adjacent the opening therein for receiving the sleeve 14.

BoXings 16 are positioned in the ends of the sleeve 14 and are provided with flanges 17 engaging the end walls of the outer drum 12. A bolt 18 or other securing device is positioned through the sleeve 1 1 and boxing 16 for securing these parts rigidly together.

The space between the outer and inner drums 12 and 13, respectively, is filled with a plastic composition such as cement for i11- creasing the weight of the rollers at a minimum cost. The inner and outer drums are also provided with registering openings 19, the space between which is left open whereby a suitable filling of cement or gravel may be placed within the drum to increase the weight thereof when desired.

Reinforcing plates 20 are embedded in the cement between the ends of the drums 12 and 13 and are adapted to receive the ends of the sleeve 14 to brace the latter, as can readily be seen from Figs. 2 and 3 of the drawings, said plates approximately extending the diameter of the inner drum for this purpose.

U-shaped collars 21 are removably positioned over the shaft 8 between the brackets 6, and are secured thereover by a cotter pin 22 or similar device. The collars 21 are adapted to be positioned between the outer ends of the rollers 11 and the outer bearing blocks 7 when ordinary rolling or pulverizing of land is done. When it is desired to separate the rollers to straddle a row, the collars are placed between the adjacent ends of the rollers 11 and the intermediate bracket 6.

Referring to the modification shown in Fig. 4, 25 indicates the inner drum which is similar in construction to the inner drum 13 described in the foregoing. The numeral 26, however, indicates an outer drum having peripheral corrugations which form is spe cially adapted for crushing clods. I desire it to be distinctly understood, however, that I reserve the right to make the body of my improved roller with or without the outer cover of sheet metal, as said outer cover may be wholly omitted if desired and the cement surface left for direct contact with the soil. 1 may in some instances leave 011 the metal covering from the face of my roller or from the ends thereof as I may deem most desirable in practice. I reserve the right, therefore, to employ the sheet metal covering upon the entire surface of the roller, or it may be omitted from the ends thereof and used upon the corrugated or smooth face, or it, may be omitted from the corrugated or smooth face and used upon the ends, all of which is obvious and Which I desire to cover and protect in this application, and I therefore deem it unnecessary to illustrate in the drawings the omission of said metallic rein: forcement.

Believing that the advantages, construction and operation of my invention have thus been made clearly apparent further description is deemed unnecessary.

What I claim is 1. A roller comprising a shaft, a sleeve surrounding said shaft, boxings secured in the ends of said sleeve, an inner cylindrical drum surrounding said sleeve, an outer cylindrical drum surrounding said inner drum said sleeve, an inner drum surrounding said sleeve, an outer drum surrounding said inner drum and disposed in spaced relation thereto, securing means extending through said sleeve and boxings, the ends of said outer drum being bulged inwardly to accommodate said securing means, and a plastic filling between said inner and outer drums.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
